I have a thought.......... has anyone ever looked at a stock D P for an STi? The hot exhaust has to make a sharp right to go down to the D P. If you install a bellmouth which directs all exhaust more efficiently. Explain how making the WASTE GATE be able to flow more waste exhaust cause Boost to Spike? The size of the wastegate has not changed.
If you know how a turbo works it doesnt make sense. I will tell you why....... you have a set amount of boost, lets say 15 psi. You have the exhaust driving the turbine. Turbine speeds up. uh oh too much boost. wastegate now says too much boost lets open UP and now redirect exhaust to Slow the speed of the turbine. Now it is capable of being open for a shorter peroid of time due to the better flow.

How can that make the turbine spin faster and spool up quicker than it programed to, If it can remove exhaust faster?

The problem is the turbo, thats why when you port the turbo creep will go buh bye.

LOUD NOISES

this topic has been debated for a while and most of the really smart subaru people agree that the problem is with the wastegate itself.

yes he is right it is you should look in to a EWG , since i got mine it stoped the creep100%. if you want one give worldoneperformance.com a call they sell the element tuning ones with a turbo smart WG and the uppipe and the dump tube for $650 the + is you can use it when you buy a new turbo if its a bolt on.
thats what i did i used it for 5 months with the stocker tell i bought the fp_REd
